Abstract :
There are two proposed methods in this paper, one is two port BDC (bidirectional dc-dc converter) while the other is three port BDC. Both converters work on the principle of bidirectional power flow while the three port BDC under soft-switching condition. The DAB (Dual active bridge) which acts as an interface between energy storage devices (Battery or Ultra-capacitor) and electrical power network. Multi-winding transformer is used for galvanic isolation between source & load. The circuit uses phase-shift control of three active bridges connected through a three-winding transformer and a network of inductors. The circuit has been simulated using MATLAB Simulink. Simulation results are verified.
